Examples
The following example shows a simple button that, when clicked, opens a <dialog>
containing a form via the show()
method. From there you can click the Cancel button to close the dialog (via the HTMLDialogElement.close()
method), or submit the form via the submit button.
<!-- Simple pop-up dialog box, containing a form -->
<dialog id="favDialog">
<form method="dialog">
<section>
<p><label for="favAnimal">Favorite animal:</label>
<select id="favAnimal" name="favAnimal">
<option></option>
<option>Brine shrimp</option>
<option>Red panda</option>
<option>Spider monkey</option>
</select></p>
</section>
<menu>
<button id="cancel" type="reset">Cancel</button>
<button type="submit">Confirm</button>
</menu>
</form>
</dialog>
<menu>
<button id="updateDetails">Update details</button>
</menu>
<script>
(function() {
var updateButton = document.getElementById('updateDetails');
var cancelButton = document.getElementById('cancel');
var dialog = document.getElementById('favDialog');
dialog.returnValue = 'favAnimal';
function openCheck(dialog) {
if(dialog.open) {
console.log('Dialog open');
} else {
console.log('Dialog closed');
}
}
// Update button opens a modal dialog
updateButton.addEventListener('click', function() {
dialog.showModal();
openCheck(dialog);
});
// Form cancel button closes the dialog box
cancelButton.addEventListener('click', function() {
dialog.close('animalNotChosen');
openCheck(dialog);
});
})();
</script>
